Thesys is an advanced frontend infrastructure solution designed specifically for developers and teams building AI-powered products. By providing a dedicated Generative UI API, the platform enables the creation of dynamic, real-time user interfaces that adapt to user interactions on the fly. Rather than relying on static components, Thesys allows applications to render custom, context-aware UI elements dynamically generated by AI models. This infrastructure helps bridge the gap between complex AI backends and seamless user experiences, making it easier for engineering teams to deploy interactive, responsive frontends without rebuilding their interface architecture from scratch. It is particularly valuable for startups and software engineers looking to elevate their AI applications, offering a robust set of tools to streamline UI development, improve frontend responsiveness, and integrate real-time capabilities directly into their software ecosystem.
Problem: AI chat assistants traditionally reply with raw text or markdown tables, which are difficult for users to interpret at a glance.
Solution: Thesys translates LLM responses into interactive charts, graphs, and dashboards in real time.
Example: A financial AI assistant generates a live, interactive stock comparison chart instead of a text list of numbers.
Problem: Users often need to fill out complex forms that change dynamically based on their specific conversational context or previous selections.
Solution: Thesys enables the LLM to output functional, interactive React forms directly in the chat interface.
Example: An AI travel planner generates a tailored booking form with fields adjusted to the user's specific itinerary requirements.
Problem: Generating multi-page reports or slideshows from an AI usually requires downloading files and opening external tools.
Solution: Thesys provides a dedicated Artifacts API to render live, editable slides and reports directly inside the application's viewport.
Example: A marketing copilot builds and displays a pitch deck within the chat window, letting the user edit slides on the fly.
Target audience: Best for: AI software developers, Frontend engineers, Product teams building AI agents

Thesys is an open source frontend infrastructure tool designed for developers building AI products. It features a Generative UI API that turns model responses into dynamic, real-time React interfaces rather than static text responses or raw markdown tables.
Thesys allows applications to stream and render context-aware user interface components dynamically. It supports interactive data visualizations like charts and dashboards, contextual React forms, and live editable documents and slides using its built-in Artifacts API and database tool call integrations.
Thesys provides an OpenAI-compatible API endpoint middleware and a React software development kit. This setup allows engineering teams to plug it into their existing model backends and render tailored UI components directly within their frontend applications.
Thesys operates under an open source pricing model. Developers and software teams can access and implement the infrastructure within their projects without paying commercial software licensing fees.
